LISTER.

Specification of Letters Patent. Patented J fine 10, 1913, Application filed October 12, 1911. Serial No; 654,402.

To all whom it may concern:

Be it known that I, LEWIS E. WATERMAN, a c1t1zen of theUnited States, residing at Rockford, in the county of Winnebago and State of Illmois, have invented certain new and useful Improvements in List ers, of which the following is a specification.

The object of this invention is to support two furrow openers and two seed dropping bars 5 and 6 have theirforw'ard ends connected to a cross-bar 7'by the bolts 8 and 9 respectively. To each of the side-bars 5 and 6 is secured a bar 10 and 11 respectively, and these bars are connected by the clamps l2. Brace-bars 13 and 14 have one end connected to the side-bars 5 and 6 respectively,"

and their other ends are connected to. the bars 10 and 11 respectively. The cranked axle 1 is'connected to the side-bar 5 and to the brace-bar 13. The cranked .axle 2 is lconnected to the sidebar-6', and to the brace- 3O are such as to permit of an oscillatory movebar 14. The connections of the crank axles ment of the cranked axles. The side-bar 5 hasa corner brace-bar 15 which supports a toothed segment 16, and a hand lever 17 has the usual dog engagementwith the toothed segment. An arm 18 has a connection with the cranked axle 1, and a link 19 connects this arm with the hand lever 17. A spring V "20 has one end connected to the arm 18 and its other end is connected to the cross-bar 7. The side-bar 6 has a corner brace-bar 21. which supports a toothed segment 22, and a hand lever 23 has the usual dog engagement with the toothed segment. An arm 24 has aconnection with the cranked axle 2, and a link 25 connects this arm with the hand lever 23. A spring 26 has one end connected to the arm and its other end is connect-ed to the cross-bar.

The forward end of the frame 1s supported by the truck 27 having a connection with the crossbar 7 through the arched ar 28, from which extend rests 29. A seat support-.30 has'one end connected tothe ross-bar 7 and supports a seat 31. The

side-bars 5 and 6 each support a seed box 32 and 33 respectively, and a shaft 34 serves to, operate the seed dropping mechanism.

A sprocket wheel 35 rotates with the supporting wheel 4. A yoke 36 is supported loosely on the cranked axle 2, and it supports a short shaft 37 to which are'connected two sprocket wheels 38 and 39. A chain 40 connects the sprocket wheels 35 and 38. A link 41 connects the shafts 34 and 37. A chain 42 connects the sprocket wheel 39 wlth a sprocket 'wheelf43 mounted on the shaft 34 and which has a connection with this shaft through the clutch 44.

By means of the hand-levers 17 and 23 the cranked-axles 1 and 2 can be rocked which will raise or lower the frame thereby raising or lowering the furrow openers 45 and 46 and the seed "dropping mechanisms, the truck 27 serving to support the forward portion of the frame. When the frame is raised or lowered it can be held in this position by the hand-levers engaging the toothed segments 16 and 22. By loosening the clamps 12 and taking out the bolts 8 and 9,

the side-bars 5 and 6 can be adjusted toward each other which will also move the seed boxes, wheels 3 and 4; The links 41 will hold the shaft 37 the same distance from the shaft 34 in order that the chain 42 will remain tight.

I claim as my invention.

1. In a machine of the character set forth, the combination with a frame comprising a front cross bar, longitudinal side bars adjustably connected attheir front ends to the front cross bar, and inwardly extending rear bars carried by the longitudinal bars and -adjustably overlapped, of means forconfurrow openers and supporting necting the overlapping portions-of the rear cross bars, a truck located in front of the front cross bar and having a connection for both side bars, independent rear suppoi'ting Wheels for the side bars, cranked axle mountings'for the Wheels journaled 0n the side bars, means for swinging the cranked axles, seeding mechanisms carried by the v side bars, a gear connection between one of V the rear Wheels and the seeding mechanism, lncludlng sprocket chzuns, and means for mamtalnmg the sprocket chains at substantially the same degree 0f tightness irrespec 10 tiveof the adjustment of the frame. n

In testimony 'whereof I have hefeunto'set my hand in presence of two subscribing witnesses.
